The primary object of my invention is to produce superlor rolls rapidly, economically and accurately.

The characterlstic features of the invention are disclosed inthe following descriptions and the accompanying drawings setting forth a form of mechanism used in the practice of the same;

p In the drawings, Fig. 1 is a broken front elevation of mechanism used in the practice of the invention; Fig. 2 is a broken side elevation of details illustrated in Fig. '1 for rough turning the rolls; Fig. 3 illustrates a broken side elevation of mechanism for the finishing turning of the rolls;' Fig. 4

is-a broken side elevation of details of the mechanism used for burnishing the rolls following the finishing turning operation; and Fig. 5 is a broken side elevation in illustration of details of the'mechanism for cutting off the burnished rolls.

The mechanism shown in the drawings,-

for the purpose of illustrating the invention, comprises a revoluble head 1, which 2 to turn the same to the rough roll form 3*.

'A finishing turning tool, comprising a roller 7 carried by the bearing 8 (which is adjustable. in the slide 9 transversely to the axis of the .chuck 2 to support the roll 3 revolved thereby) and a cutter 10 carried by a slide 11 (which is adjustable in the slide 9 transversely to the axis of the chuck),

conforms to the contour desired in the roll 3'. The slide 9 is movable in the guide 12 finishing turning operation simultaneously with the rough turning of the ro1l3' A burnishing. tool is formed by the,

burnishing rollers 13 and 14 carried by the respective slides 15and 16', which .are ad- 7 justable in the'slide 17 (laterally with relation to the axis of the chuck 2" for revolving the roller 3) to eifect the desired pressure of the burnishing rollers on the-roll to be consolidated and finished thereby, the slide 17- being movable in the way 18 so that the roll 3 will pass between the rollers 13 and 14 as theyare moved transversely to and in contact'with the roll;

A cutting tool 19 is carried by a holder 20 set in the slide 21 which is movable in the way 22 transversely to the axis of the chuck 2' to cut oil" the burnished and finished roll 3?. as it is turned by the chuck in contact with the tool. I

In. the operation of the device, the chucks 2, 2, 2' and'2- are revolved simultaneously in-the stationary head 1 (by well known means not shown)'to perform the-operations of rough turning, finishing turning, burnishing and cutting off the respective rolls .3 3 3 and 3 The respective operations on these rolls having been completed, the slides 5, 9, 17 and 21 are retracted, and the head '1 is turned through a quadrant to bring the roughly turned roll 3 into position for the,

finishing, turning operation, the finally turned roll 3 into position. for the burnishing operation and the burnished roll 3 into position for the cutting off operatio'n, the rod from which the roll is. cut being moved forward for engagement .in its next position with the rough turning tool.

Having described my invention, I claim: 1. The process of forming bearing rolls which comprises the sequential operations of revolving the stock successively in contact with a turning tool, a burnishing tool and a cutting off tool.

2. The process of forming bearing rolls which comprises the sequential operations of revolving the stock in contact with turning mechanism and between burnishing rollers which are moved transversely to the axis of the revolving stock.

-3. The process of forming bearing rolls which comprises the operations of revolving 'said rolls-between burnishing rollers having a motion of revolution in contact with and a motion of translation across said rolls.

4] The combination with a revoluble head and revoluble work holders carried'thereby, of a roughing cutter, a finishing cutter, a

burnishing tool and a cutting ofi tool arsaid holder revolves said work, andmeans for moving said rollers in contact with and transversely to said work. o

' 6. The combination with turning mechanism and burnishing mechanism; of means for revolving work first is contact with said turning mechanism. and thereafter inconran edto act simultaneously on "work carrie by said holders."

5."The combination of'a revolublework holder, burnishing rollers between which
